Abstract

The invention provides a method and a system for parking space detection. The method for parking space detection comprises that according to a computing interval arranged in advance, after a geomagnetism parking space detector obtains a geomagnetism induction intensity value of parking space in the Tth computing interval, the geomagnetism parking space detector obtains a calibration value in the Tth computing interval, wherein T is a positive integer, the geomagnetism induction intensity value obtained by sampling is compared with the corresponding calibration value in the Tth computing interval, a result is obtained, according to an output strategy arranged in advance and the result, and information that whether the parking space is in use is output.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for detecting a parking space. Background technique [0002] With the rapid development of the city's economic scale and the continuous improvement of citizens' living standards, the number of various vehicles in the city, especially private cars, continues to increase. Problems such as difficulty in finding parking lots, tight parking spaces, and time-consuming waiting for seats have always plagued the public. Therefore, a parking lot guidance system has emerged, which detects the status of parking spaces through geomagnetic parking space detectors, releases parking space information, and guides the public to park. [0003] The geomagnetic parking space detector is a sampling geomagnetic sensor to monitor the changes in the geomagnetism of the parking space in the two states of car and no car, so as to realize the judgment of the presence or absence of vehicles. If...
